Neste trabalho, verificou-se a influência de fatores edáficos na estrutura populacional de cinco espécies arbóreas em duas fitofisionomias do bioma Cerrado na Fazenda Experimental do Moura em Curvelo – MG. Na área de estudo, em 2010, foram alocamos 25 parcelas de 20 x 50 metros, separadas entre si por 100m, sendo 15 parcelas no Cerrado sensu stricto e 10 no Cerradão. Foram identificados e medidos todos os indivíduos arbóreos vivos com diâmetro altura do solo (DAS) ≥ 5,0 cm, e coletadas amostras de solo em todas parcelas amostradas, para realização de análises química e granulométrica. Foram selecionadas as cinco espécies mais abundantes na área de estudo, e utilizou-se análises de correlação de Pearson para verificar as relações solo-vegetação destas populações. Os resultados mostraram correlações significativas (positivas e negativas) entre as variáveis: P, M.O., pH, K, SB, m, K, Areia, Silte e Argila e as espécies amostradas, além de diferenças entre ambientes. Considerando-se as relações existente entre as espécies e as variáveis ambientais, pode-se concluir que as populações investigadas, apresentaram variações na densidade ao longo das duas fitofisionomias. Tal informação reforça a ideia de que embora as fitofisionomias pertençam ao mesmo bioma e que apresentam espécies em comum, as populações precisam se adaptar às condições microambientais existentes em cada fitofisionomia.Palavras-chave: variáveis edáficas; relação solo-vegetação; densidade. ENVIRONMENTAL INFLUENCE IN THE STRUCTURE OF POPULATIONS OF CERRADO  IN THE CENTRAL REGION OF MINAS GERAIS ABSTRACT: The present study aimed to generate information on the ecology of important populations in two Cerrado biome Phytophysiognomies in the Experimental Farm of Moura in Curvelo - MG. An inventory was carried out in 2010, with 25 parcels being systematically allocated with dimensions of 20 x 50 meters, separated from each other by 100m. All living arboreal individuals with soil height diameter (DAS) ≥ 5.0 cm were identified and measured. In all plots of each phytophysiognomy soil samples were collected to determine the chemical and granulometric analyzes to be used in Pearson correlation analysis (vegetation and environment) in order to understand the possible relationships. The results of the analyzes showed that there were significant correlations between the variables P, M.O., pH, K, SB, m, K, Sand, Silt and Clay. Considering the diametric structure and the relationships between the species and the environmental variables, it can be concluded that the populations investigated showed variations in density along the two phytophysiognomies. This information reinforces the idea that although the phytophysiognomies belong to the same biome and that they have species in common, the populations need to adapt to the environmental conditions of each phytophysiognomy.Keywords: edaphic variables; soil-vegetation ratio; density.

Abstract Background: Long non-coding RNAs (lncRNAs) play an important role in angiogenesis, immune response, inflammatory response and tumor development and metastasis. m6 A (N6 - methyladenosine) is one of the most common RNA modifications in eukaryotes. The aim of our research was to investigate the potential prognostic value of m6A-related lncRNAs in ovarian cancer (OC).Methods: The data we need for our research was downloaded from the Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) database. Pearson correlation analysis between 21 m6A regulators and lncRNAs was performed to identify m6A-related lncRNAs. Univariate Cox regression analysis was implemented to screen for lncRNAs with prognostic value. A least absolute shrinkage and selection operator (LASSO) Cox regression and multivariate Cox regression analyses was used to further reduct the lncRNAs with prognostic value and construct a m6A-related lncRNAs signature for predicting the prognosis of OC patients. Results: 275 m6A-related lncRNAs were obtained using pearson correlation analysis. 29 m6A-related lncRNAs with prognostic value was selected through univariate Cox regression analysis. Then, a seven m6A-related lncRNAs signature was identified by LASSO Cox regression. Each patient obtained a riskscore through multivariate Cox regression analyses and the patients were classified into high-and low-risk group using the median riskscore as a cutoff. Kaplan-Meier curve revealed that the patients in high-risk group have poor outcome. The receiver operating characteristic curve revealed that the predictive potential of the m6A-related lncRNAs signature for OC was powerful. The predictive potential of the m6A-related lncRNAs signature was successfully validated in the GSE9891, GSE26193 datasets and our clinical specimens. Multivariate analyses suggested that the m6A-related lncRNAs signature was an independent prognostic factor for OC patients. Moreover, a nomogram based on the expression level of the seven m6A-related lncRNAs was established to predict survival rate of patients with OC. Finally, a competing endogenous RNA (ceRNA) network associated with the seven m6A-related lncRNAs was constructed to understand the possible mechanisms of the m6A-related lncRNAs involed in the progression of OC.Conclusions: In conclusion, our research revealed that the m6A-related lncRNAs may affect the prognosis of OC patients and identified a seven m6A-related lncRNAs signature to predict the prognosis of OC patients.

This article examines the relationship between learning and behavioural evaluation among religious officers in Malaysia after attending the Manual on HIV/AIDS in Islam Training Programmes organized by the Islamic Development Department of Malaysia (JAKIM). The training programmes were implemented to deliver the most accurate and the latest information on HIV / AIDS as well as to train religious officers in Malaysia to address the issues among Muslims. The training programmes apply the theoretical and practical activities where participants had the opportunity to carry out outreach activities with People Living with HIV / AIDS (ODHA). Quantitative methods through questionnaires were used to obtain data. A total of 350 religious officers who had attended the training programmes were selected as respondents by simple random sampling technique. Pearson correlation analysis was conducted to determine the relationship between the learning and behavioural evaluation. The results of the Pearson correlation analysis found that there was a significant relationship between learning evaluation in terms of the information obtained from programmes’ contents and behaviour evaluation with r = 0.489 and sig = 0.000 (p <0.05) at the medium positive range.. While the relationship between learning evaluation in terms of the information obtained from outreach activities with behavioural evaluation showed a strong positive correlation with the strength values obtained were r = 0.539 and sig = 0.000 (p <0.05). This analysis shows that the information acquired through the training program Manual Islam and HIV / AIDS has been successful in changing the behaviour of religious officers’ awareness in terms of the role of dakwah to ODHA.

In the current study, a total of 86 soccer’s players with mean age of 14 years drawn from Terengganu soccer academy were tested in performing 10 parameters aiming at determining the performance of those players based on assessing the contribution of each activity and its corresponding significant level. The 10 performance related parameters involved anthropometry (BMI), fitness test (agility, coordination, muscular endurance (push and sit up), power, YoYo level), and football skill test (dribbling with ball, dribbling without ball and juggling).  All the parameters testing is carried out based on international standard and performed by well-trained staff.  The Pearson correlation analysis was used to achieve the objective in this study. Result shows a positive correlation between the two types of muscular parameters; the power is influenced by BMI and coordination; the specific football tests are highly impacted by the power and agility. The coefficient of determination  and the significance level -values show that the parameters that can be significantly considered are the anthropometric BMI (0.020), agility (0.025), muscular endurance (0.039 and 0.043), power (0.039), special football test without the ball (0.041), and juggling (0.046). The coordination, YoYo, football special test with the ball were not found to be significantly accounted for preparing the young players to achieve the required performance. Based on the results of the coefficient of determination and the significance -values of the parameters, a model was proposed to determine the highest and lowest parameters that play important roles in the selection of young players.

Groundwater Dynamic

In the past few decades, the shrinkage of the Aral Sea is one of the biggest ecological catastrophes caused by human activity. To quantify the joint impact of both human activities and climate change on groundwater, the spatiotemporal groundwater dynamic characteristics in the Amu Darya Delta of the Aral Sea from 1999 to 2017 were analyzed, using the groundwater level, climate conditions, remote sensing data, and irrigation information. Statistics analysis was adopted to analyze the trend of groundwater variation, including intensity, periodicity, spatial structure, while the Pearson correlation analysis and principal component analysis (PCA) were used to quantify the impact of climate change and human activities on the variabilities of the groundwater level. Results reveal that the local groundwater dynamic has varied considerably. From 1999 to 2002, the groundwater level dropped from −189 cm to −350 cm. Until 2017, the groundwater level rose back to −211 cm with fluctuation. Seasonally, the fluctuation period of groundwater level and irrigation water was similar, both were about 18 months. Spatially, the groundwater level kept stable within the irrigation area and bare land but fluctuated drastically around the irrigation area. The Pearson correlation analysis reveals that the dynamic of the groundwater level is closely related to irrigation activity within the irrigation area (Nukus: −0.583), while for the place adjacent to the Aral Sea, the groundwater level is closely related to the Large Aral Sea water level (Muynak: 0.355). The results of PCA showed that the cumulative contribution rate of the first three components exceeds 85%. The study reveals that human activities have a great impact on groundwater, effective management, and the development of water resources in arid areas is an essential prerequisite for ecological protection.

We analyzed the effects of air leakage and other building characteristics on outdoor particle penetration in classrooms. The building characteristics including air leakage of 12 Korean schools were investigated, and onsite measurements were conducted to estimate the outdoor particle infiltration. The correlations among variables associated with air leakage and building characteristics and outdoor particle infiltration were analyzed using the Pearson correlation analysis and linear regression. The effective leakage area (ELA) of classrooms varied highly from 340.8–1566.9 cm2, and a significant disparity in the air leakage characteristics among the classrooms appeared. The results of onsite measurement revealed that the average ELA was larger in the corridor side with an ELAcorridor-side of 264.7 cm2 than in the outdoor side (ELAoutdoor-side of 93.1 cm2). Results of correlation analysis indicated a high correlation (r = 0.68~0.78, p-value < 0.05) between the size resolved outdoor particle source (P × λ) and specific ELA. Particularly, a strong linear relation (R2 = 0.69~0.71) with specific ELAcorridor-side was seen. Results suggest that cracks between windows and doors in the corridor side considerably affect outdoor particle penetration. These results indicate the importance of improving the airtightness of not only the building envelope but also the inter-zonal walls for effectively reducing the outdoor particle infiltration into classrooms.

Acute lung injury represents a widespread, variable type of lung injury characterized by a low oxygen level in the blood, non cardiogenic pulmonary edema, low lung compliance and extensive capillary leakage. In our study, the Wistar rat mode of ALI was established using lipopolysaccharide (LPS). The rats were randomly divided into normal control (NC) group (n = 12) and miR-16 overex-pression group (n = 12), and they were transfected with empty vector and miR-16 overexpression virus, respectively. The lung tissues were extracted in both groups, and then the expression levels of miR-16 and NF-κB were detected via fluorescence quantitative reverse transcription-polymerase chain reaction (qRT-PCR), and the association between their expressions was analyzed via Pearson correlation analysis. Moreover, the morphological changes in lung tissues were detected via hematoxylin-eosin (HE) staining, and the differences in the wet/dry weight (W/D) ratio and the pathomorphological score of lung tissues were compared between the two groups. The expression level of NF-κB was detected via immunohistochemistry (IHC) and Western blotting. Our results showed that, there were different degrees of lung injury in lung tissues in both groups. In miR-16 overexpression group, the W/D ratio was significantly higher than that in NC group (P < 0.05), and the pathomorphological score was also significantly higher than that in NC group (P < 0.05). The results of RT-PCR revealed that the mRNA levels of miR-16 and NF-κB in miR-16 overexpression group were 2.5 and 3.7 times higher than those in NC group. The results of Western blotting and IHC also showed that the activity of NF-κB in lung tissues was evidently enhanced in miR-16 overexpression group compared with that in NC group. According to the Pearson correlation analysis, there was a significant positive correlation between the mRNA levels of miR-16 and NF-κB in lung tissues (r = 0.705, P = 0.012). In conclusion, miR-16 activates the NF-κB pathway to initiate a series of inflammatory responses, thereby contributing to the occurrence of ALI in rats.
